All - I have sent detailed data to the tools team and Henrik, but I wanted to alert everyone to a pattern I've seen during my analysis: This request: POST /doc/draft-ietf-payload-rfc3016bis/edit/position/ HTTP/1.1" 302 - https://datatracker.ietf.org/doc/draft-ietf-payload-rfc3016bis/edit/position/ was seen in the logs at the start of both slowdowns, and I now suspect that there may be database corruption and/or some problem with the code related either to ballot positions generally, or this draft specifically. It comes to my mind that, while I was gone, a request came in to clear the ballot positions for a draft, which the secretariat did. This may have been the draft that was cleared - and clearing it may have caused some type of problem for the datatracker. Of course, the datatracker should not loop or fail even if data is bad, but not all possibilities can be forseen. It is my hope that we will both be able to correct a potential database problem, and find and harden a potential datatracker bug, quickly. In the meantime, until we hear from the tools team, it might be best to at least refrain from voting on the above draft, if not all drafts. If you do vote on a draft, and get a response, don't get too excited either way. The server actually survives for an hour or more once the bug starts using resources (I'm actually proud of this - it's a HUGE server with lots of resources - the old servers would have died much more quickly. ;-) so things can appear okay for a while. Now that we know what to look for, we can catch it earlier, but I'm still hopeful for a quick fix and repair today. Thanks, Glen
